Can you tell me how we will select RTD and Thermocouples for
Temperature applications. I.e How we will choose accurate
one for a specefic operation if both having same ranges

Both thermocouples and RTD have their specific advantages,
according to our need we have to choose for our purpose.i am
explaining below:
1.thermocouples can measure up to a temp. of 1700 degree
celcius,where as RTDs are limited to 800 degree celcius
2.Grounded Thermocouples are inheritantly tip sensitive;
while RTD elements are isolated from their sheaths. A
grounded Thermocouple will respond to a 63% step change in
temperature nearly 3 times faster than a RTD counterpart.
3.Normally rtds are costlier i.e.2.5 or 3 times than
thermocouples
4.as the case is taken onbehalf of accuracy and linearity
RTD shows improve characteristics than thermocouple.
5.Due to their linearity and virtually drift free output,
RTDs are more stable than Thermocouples.
